＜正＞Due to the special security requirements and abominable environment,researching in the high reliability of the communication network and power in coal mine monitoring system is become special important.The reliability of the communication network and power in the coal mine monitoring system has been studied.To assess the reliability of the underground power and communication network,the constant stress accelerated life tests was presented based on the exponential distribution.The voltages and temperature were chosen as the constant accelerated stress parameters.Through the analysis of experimental data,the average life expectancy curves were obtained under different temperatures and voltage.With overall consideration of the communication network topology structure and network capacity the improved EED-SDP method was put forward in coal mine monitoring.It is concluded that reliability analysis of power and communication network in coal mine monitoring system is remarkably important to improve the reliability of coal mine monitoring system.

This paper suggests a combined novel control strategy for DFIG based wind power systems(WPS)under both nonlinear and unbalanced load conditions.The combined control approach is designed by coordinating the machine side converter(MSC)and the load side converter(LSC)control approaches.The proposed MSC control approach is designed by using a model predictive control(MPC)approach to generate appropriate real and reactive power.The MSC controller selects an appropriate rotor voltage vector by using a minimized optimization cost function for the converter operation.It shows its superiority by eliminating the requirement of transformation,switching table,and the PWM techniques.The proposed MSC reduces the cost,complexity,and computational burden of the WPS.On the other hand,the LSC control approach is designed by using a mathematical morphological technique(MMT)for appropriate DC component extraction.Due to the appropriate DC-component extraction,the WPS can compensate the harmonics during both steady and dynamic states.Further,the LSC controller also provides active power filter operation even under the shutdown of WPS condition.To verify the applicability of coordinated control operation,the WPS-based microgrid system is tested under various test conditions.The proposed WPS is designed by using a MATLAB/Simulink software.

This paper presents engineering experiences from battery energy storage system(BESS)projects that require design and implementation of specialized power conversion systems(a fast-response,automatic power converter and controller).These projects concern areas of generation,transmission,and distribution of electric energy,as well as end-energy user benefits,such as grid frequency regulation,renewable energy smoothing and leveling,energy dispatching and arbitrage,power quality and reliability improvements for connected customers,islanding operations,and smart microgrid applications.In general,a grid level BESS project sends an interconnect request to utility power grids in the project development stage.Simulation models of equipment are then sent for a system impact study(e.g.,power flow and/or stability analysis),based on utility grid code requirements.The system study then determines the connection’s technical feasibility and impact of the project on the power grid.In this paper,a set of new BESS models is presented that are configured and parameterized for use in system impact studies as well as transmission planning studies.The models,which have been recently approved and released by the U.S.Western Electricity Coordinating Council(WECC),represent the steady state and dynamic performance of the BESS in several software platforms for power system studies based on operating project performance experience.Model benchmarking results as well as a real system case study are also included in the paper to show that the parameterized and tuned models respond correctly and as expected when system operating conditions change following contingency events.Finally,this paper provides useful guidelines in the use of new models to represent a BESS for power system analysis.
